fix: JSDoc build

[d3xter666]

The JSDoc configuration was set to exclude specific files containing custom UI5 tags (like @ui5-restricted) that aren't recognized by JSDoc. However, these exclusion patterns weren't working in the monorepo setup.

With npm workspaces, dependencies can be installed in multiple locations:

• Root level: ../../node_modules/@ui5/ (relative to the documentation package)
• Package level: ./node_modules/@ui5/ (within the documentation package itself)

The original jsdoc.json only had exclusion patterns for the root-level path. When npm installed @ui5/builder-npm at the package level, the excluded files (like JSTokenizer.js) were still being processed. Since these files use the custom @ui5-restricted tag and allowUnknownTags: false was configured, JSDoc failed on encountering these unknown tags.
